    Abstract: An infrared detector is scanned over a field of view generating an infrared video signal based on the intensity of the infrared radiation appearing in the field of view, which signal is utilized to provide a thermal image of the field of view. After sufficient amplification, the infrared video signal is fed to a peak detector which derives a signal based on the maximum or minimum signal level in the infrared video signal which is coupled to an error amplifier and reinserted in the processing channel for controlling the brightness of the scene to be displayed.
